MD03 TECs for Cooled TOSA. A range of miniature single-stage
thermoelectric coolers specially optimized for cooled TOSA applications by
power consumption. Low-current, less than 1.0mm height thermoelectric
coolers fit ideally for TOSA components in XFP and SFP+ transceivers with
strict power consumption limits. Various dimensions for TO-can TOSA and
box MSA TOSA are available. Thin ceramics and Wire Bonding contacts are
applied as standard. Read the introduction here.

MD04 TECs for Cooled TOSA. A range of miniature single-stage
thermoelectric coolers based on MD04 Series and designed specially for
cooled TOSA applications. These types are designed specially for coaxial
TOSA and box-like TOSA MSA. Various dimensions and performance solutions
are available. Each thermoelectric cooler type has six height and performance
options. Thin ceramics and Wire Bonding contacts are applied as standard.
Ultra-thin Thermoelectric Coolers with 0.9mm total height are available with
Cooling Power Density of 25W/cm2. Read the complete overview here.

MD06 Series. High density pellets placement thermoelectric coolers with

Single-stage Thermoelectric Coolers for Telecom Applications

Thermoelectric Coolers from this Series are specially optimized for cooling in DWDM applications. Typical telecom standard TECs of 17, 23, 29 and 35 couples (Bi-Te elements inside TEC) are available. Each type can be provided in different ceramics options: Alumina and Aluminum Nitride with different thicknesses.

ML06 Series of Thermoelectric Coolers has been developed specially for
Telecom applications and optimized for typical telecom packages like
"Butterfly", DIL and some others. Each type has four different height/
performance options:
• Dimensions: 6.0x6.0 - 7.0x15.0 mm2
• Up to 72K dTmax
• Max Cooling Capacity - 12W
• Max Operating Current Range - 1.5 - 3.5A

Thermoelectric Coolers for Telecom Applications with increased Cooling Capacity

Based on High Density pellets placement technology thermoelectric coolers of 1MDL06 Series have about 40% more pellets (elements inside TEC) on the same size as standard thermoelectric cooler. Together with ultra-low profile pellets of 0.3mm height it increases cooling capacity of TEC more than twice. Check the review of 1MDL06 Series.

MDL06 Series of Thermoelectric Coolers has been developed specially for
Telecom applications and optimized for typical telecom packages like
"Butterfly" and DIL. Each type has six different height/performance
options:
• Dimensions: 6.0x6.0 - 7.0x15.0 mm2
• Up to 72K dTmax
• Max Cooling Capacity - 25W
• Max Operating Current Range - 1.2 - 5.3A

Thermoelectric Coolers with Special Configurations

The classical connection between Bi-Te elements (pellets) inside thermoelectric coolers is serial. The typical way to change thermoelectric coolers electrical/performance parameters is in changing of pellet Bi-Te elements) height. However, there are several ways to modify the construction of TEC and obtain results, optimized for some custom applications, using combination of different pellet heights (for multi-stage TEC types), parallel connection instead of serial or a combination of both solutions.
